He spent years barely surviving, the only thing keeping him going is getting back to his wife. And when he get's back his "friend" tells him
>She remarried bro so she's off limits, I mean sure the only reason she remarried is because she thought you were dead but if someone is married in a movie that means they're off limits, seriously.
So he goes through a bullshit press conference because he was promised at the end that he'd get to see her and her current husband comes out and basically tells him to fuck off.

Finally he gets to talk with her again and surprise surprise she still loves him so he tells her
>I love you too, you're the only thing that kept me going on that island, but you're married and it's sure to be a long one considering he's not the man you love, so goodbye.

But don't worry because that package he kept all those years belonged to a girl and since all women are interchangeable he's sure to love her as much as his wife. Roll credits.
